Abstract

Exobasidium rhododendri is a parasite of Rhododendron and also infects apples. A chromosome-level genome of E. rhododendri was assembled using the PacBio and Illumina datasets. The complete genome length is 17.6 Mb, with N50 of 5.45 Mb, and its GC content is 50.08%. The assembly obtained contains four scaffolds, including three nuclear chromosomes and one mitochondrion. There are a total of 6,982 predicted protein-encoding genes containing 406 fungal secretion proteins and 249 candidate effectors in the E. rhododendri genome. This high-quality genome will help understand the pathogenic mechanism of this fungus.

Keywords: CAZymes; Exobasidium rhododendri; candidate effector; pathogenesis.
